Paper Size; Smoothness; Basis Weight; Thickness (Caliper) - Kyocera MITA PF-60 Service Manual

(3) Paper size

The paper feeder is usable with the paper sizes as tabled below.

(4) Smoothness

The paper should have a smooth, uncoated surface. Paper with a rough or sandy surface can cause
voids in the printed output. Paper that is too smooth, however, can cause multiple feeding and
fogging problems. (Fogging is a gray background effect.)

(5) Basis weight

Paper that is too light or too heavy can cause misfeeding, jams, and premature wear of the paper
feeder and the printer. Uneven paper weight can cause multiple feeds, print defects, poor toner
fusing, blurring, and other print quality problems. The proper weight is 60 to 105 g/m
ream).

(6) Thickness (Caliper)

Thick paper is referred to as high-caliper paper and thin paper as low-caliper paper. The paper used
with the paper feeder should be neither extremely thick nor extremely thin. If you are having problems
with paper jams, multiple feeds, and faint printing, the paper may be too thin. If you are having
problems with paper jams, and blurred printing the paper may be too thick. The proper thickness is
0.086 to 0.110 mm (3.4 to 4.3 mils).

(7) Moisture content

Moisture content is defined as the percent ratio of moisture to the dry mass of the paper. Moisture
can affect the paper's appearance, feedability, curl, electrostatic properties, and toner fusing
characteristics.
The moisture content of the paper varies with the relative humidity in the room. When the relative
humidity is high and the paper absorbs moisture, the paper edges expand, becoming wavy is
appearance. When the relative humidity is low and paper loses moisture, the edges shrink and
tighten, and print contrast may suffer.
